# Mamba Basic F405 MK4 Flight Controller |
||||
|
||||
The Mamba Basic line of flight controllers are produced by [Diatone](https://www.diatone.us). |
||||
|
||||
## Features |
||||
|
||||
- STM32F405RGT6 microcontroller |
||||
- MPU6000 IMU |
||||
- AT7456E OSD |
||||
- 4 UARTs |
||||
- 7 PWM outputs (6 Motor Output, 1 LED) |
||||
|
||||
## Pinout |
||||
|
||||
 |
||||
|
||||
## UART Mapping |
||||
|
||||
The UARTs are marked Rn and Tn in the above pinouts. The Rn pin is the |
||||
receive pin for UARTn. The Tn pin is the transmit pin for UARTn. |
||||
|Name|Pin|Function| |
||||
|:-|:-|:-| |
||||
|SERIAL0|COMPUTER|USB| |
||||
|SERIAL1|PPM/RX1/SBUS/TX1|UART1 (RC Input)| |
||||
|SERIAL2|TX2/RX2|UART2 (DMA-enabled)| |
||||
|SERIAL3|TX3/RX3|UART3 (Telem1)| |
||||
|SERIAL4|TX4/RX4|UART4 (Empty)| |
||||
|SERIAL6|TX6/RX6|UART6 (GPS, DMA-enabled)| |
||||
|
||||
|
||||
## RC Input |
||||
|
||||
RC input is configured on the PPM (UART1_RX) pin. It supports all RC protocols. |
||||
|
||||
## OSD Support |
||||
|
||||
The Mamba F405 MK4 supports OSD using OSD_TYPE 1 (MAX7456 driver). |
||||
|
||||
## PWM Output |
||||
|
||||
The Mamba F405 MK4 supports up to 7 PWM outputs. The pads for motor output ESC1 to ESC4 on the above diagram are for the 4 outputs. All outputs support DShot as well as all PWM types. Motors 1-4 support bi-directional DShot. |
||||
|
||||
The PWM is in 4 groups: |
||||
|
||||
- PWM 1,2 in group1 |
||||
- PWM 3,4 in group2 |
||||
- PWM 5,6 in group3 |
||||
- PWM 7 in group4 |
||||
|
||||
Channels within the same group need to use the same output rate. If |
||||
any channel in a group uses DShot then all channels in the group need |
||||
to use DShot. |
||||
|
||||
## Battery Monitoring |
||||
|
||||
The board has a builting voltage sensor. The voltage sensor can handle up to 6S |
||||
LiPo batteries. |
||||
|
||||
The correct battery setting parameters are: |
||||
|
||||
- BATT_MONITOR 3 |
||||
- BATT_VOLT_PIN 11 |
||||
- BATT_VOLT_MULT around 11.0 |
||||
- BATT_CURR_PIN 13 |
||||
- BATT_CURR_MULT around 28 with the 20x20 40A ESC (calculated, needs to be verified) |
||||
|
||||
## Compass |
||||
|
||||
The Mamba Basic flight controllers do not have a builtin compass, but you can attach an external compass using I2C on the SDA and SCL pads. |
||||
|
||||
## Alternate settings |
||||
|
||||
It is possible to set alternate configurations with the BRD_ALT_CONFIG parameter. |
||||
|
||||
|BRD_ALT_CONFIG|RX1 function| |
||||
|:----|:----| |
||||
|ALT 0(default) |RCININT| |
||||
|ALT 1|RX1/TX1| |
||||
|
||||
## Loading Firmware |
||||
|
||||
Initial firmware load can be done with DFU by plugging in USB with the |
||||
bootloader button pressed. Then you should load the "with_bl.hex" |
||||
firmware, using your favourite DFU loading tool. |
||||
|
||||
Once the initial firmware is loaded you can update the firmware using |
||||
any ArduPilot ground station software. Updates should be done with the |
||||
*.apj firmware files. |
